Yahoo is closing its last remaining office in mainland China, the latest cost-cutting measure imposed by the struggling U.S. Internet giant.

Between 200 and 300 employees will be laid off as a result of the closure of the Beijing office, according to news reports Thursday. The office primarily served as a research and development center.

Yahoo has not offered services in mainland China since it shut down its email service there in 2013. The company turned over control of its China operations to the Chinese e-commerce company Alibaba in 2005.

Like other Western technology companies doing business in China, the California-based Yahoo has had to deal with restrictions imposed on it by the Communist Party.

Human rights groups have in the past blasted Yahoo for providing Communist authorities information that led to Chinese dissidents being convicted of anti-state activities.

But the closure of the Beijing office appears to have nothing to do with censorship or related issues, according to a Yahoo statement published by Bloomberg.

"We are constantly making changes to align resources and to foster better collaboration and innovation across our business," the statement said.

Investors have been pressuring Yahoo to reduce costs, amid plunging profits. In recent weeks, Yahoo has cut workers in Canada, India, and Jordan.
